RAILWAY-CAR TRUCK.

Specification of Letters Patent.

Patented June 1 5, 1909.

Application filed September 24, 1906. Serial No. $35,924:.-

To all whom it may concern: Be it known that I. Gnonon G. FLOYD, a citizen of the United States, residing at Granite, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Railway-Car-Trncks, of which the following is a specification. My invention relates to railway car trucks and its main object is to provide means whereby the bolster may be readily removed from the truck and disconnected from the side frames.

In my preferred construction each side frame 1s cast in one piece and is provided with a central aperture or opening through which an end of the bolster projects. At the bottom of this opening the side is broadened so as to provide a wide spring seat, springs being interposed between this seat and the under side of the end of the bolster. To pre vent lengthwise movement of the bolster I supply it on its upper side or surface near each end with guiding lugs adapted to fit on opposite sides of that portion of the side frame over the aperture. Under normal working conditions these lugs prevent the bolster from shifting longitudinally, but in case it is desired to withdraw the bolster the springs are removed, allowing the bolster to drop s'ulliciently to enable it to be withdrawn 1 from the side frame, the lugs on its upper face escaping that part of the frame-over the aperture.

Another object of my invent-ion is the provision of means for the attachment of the transoms or transverse beams to the side frames. For this purpose I preferably use,

in connection with inwardly projecting walls, shelves with brackets integral with the side frame and extending inwardly from the plateor vertical web portion of the frame.

I have illustrated the preferred embodiment of my invention in the accompanying drawings, wherein,

Figure 1 is a side elevation of my improved and novel side frame; F 2 is a plan view of the structure shown in Fig. 1; Fig. 3 ,is a section longitudinally -of the bolster and transversely of the side frame on an enlarged scale; and Fig. 4 is a transverse section of theside frame on line H of Fig. 1.

, The sideframe of the car truck includes a main plate or vertical Web 10 triangularly.

and circularly apertured at 11 and 12 for the purpose of producing a structure of minimum weight consistent with suflieient strength. The topedge of plate 10 is bowed upwardly and has flanges 13 extended therefrom its opposite directions. At its central part this plate or web has a rectangular opening 141 adapted to-receive the end of the bolster and the bolster springs. Above this opening or aperture flange 13, which at this portion becomes a web, is provided on vboth edges with a downwardly extended flange 15, the two, depending flanges being tied together at their centers by an arched web 16, shown most clearly in Fig. 3. The sides-of aperture is have outwardly extended flanges 17 and inwardly projecting flanges 18 which at their upper ends are con'sider'abl y'bnoadv ened at '19. Adjacent to the lower ends of the broadgparts of these flanges or walls are horizontal shelves 20 integral with the frame and sustained in position by integral brackets 21. venient means to which to rivet angle transoms 22. Along its bottom edgeplate 10 has a marginal flange 23 which at the bottom of recess 14 is considerablyyvidenedto provide the spring seat 24 extending inwardlysan'd outwardly from the plate 10 The top surface or face of this spring seat may desirably be supplied with round bosses 25 over which the lower ends of the bolster springs are adapted to fit. Beneath a portion of flange 23 and spring seat '24 the frame has a downwardly extended rib 26 with apertured enlargements 27 adapted to accommodate belts or the like for maintaining in position thepedestal tie-bar 29. This rib 2G and the enlargements also have, bracket ribs 30 to aid in supporting the spring seat 2-1.

The bolster springs 31 when in position rest on the spring seat and encircle the bosses 25, while the bolster has its end projecting through aperture let and in connection with the filler block 32-} rests upon the top ends of the springs 31. Units top surface bolster 32 has two transverse lugs or ribs 33 adapted to overlap flanges 15, as shown in Fig. 3, this construction preventing lengthwise moven'ient of the bolster as long as the springs remain in place. These ribs or lugs are desirably integral with the bolster and may be supplied with integral bracket supports or braces 34 to maintain them. in proper position. In order tore-- The walls 19 and shelves -20 form conmove the bolster it is merely necessary to take out the springs which permits the bolster totdescend sutlicient-ly so that lugs 33 escape flanges 15, thereby permitting the bolster to be withdrawn through aperture 14.

I claim:

v 1. In a railway car-truck, the combination of a side-frame having an aperture of substantially uniform width and adapted to accommodate the end of a bolster and a bolster whose end projects through said aperture and is of substantially the same width as said aperture, said bolster having integral therewith a pair of transverse upstanding guiding ribs or lugs adapted to lie on opposite sides of that portion of the sideframe above said aperture and eo-act therewith permitting vertical movement of the bolster but preventing longitudinal shifting thereof, said ribs or lugs and portion of said frame constituting the sole means for preventing lengthwise movementof the bolster, substantially as described.

In arailway cartruck, the combination of a side-frame having an aperture of substantially uniform width and adapted to accommodate the end of a bolster, and a bolster whose end. projects through said aperture and is of substantially the'same width as said aperture, said bolster having integral therewith a pair of transverse upstanding guiding ribs or lugs adapted to lie on opposite sides of that portion of the sideframe above said. aperture and co-act therewith permitting vertical movement of the bolster but preventing longitudinal shifting thereof, said ribs or lugs and portion of the side-frame constituting the sole means for preventing lengthwise movement of the bolster, said bolster also having integral there-v with one or more braces to strengthen said ribs or lugs, substantially as described.

3. In a railway car-truck, the combination of a side-frame having an aperture of substantially uniform width and adapted to accommodate the end of a bolster, the portion of said frame over said aperture having practically parallel flanges, and one or more transverse webs integral with and connecting said flanges, and a bolster whose end is of ed to lie on opposite sides of said flanges to co-act therewith, permitting vertical movement of the bolster and preventing longitudinal shifting thereof, said ribs or lugs and flanges constituting the sole means for preventing lengthwise movement of the bolster, said bolster also having integral therewith one or more braces to aid in maintaining said ribs or lugs in proper position and preventing their being broken off, substantially as described.

4.- In a railway car-truck, the combination of a side-frame having a bolster aperture of substantially uniform width adapted to accommodate the end of a bolster, the portion of said frame over said aperture having substantially parallel depending flanges connected together by one or more transverse webs, and a bolster whose end projects through said aperture and is of substantially the same width, said bolster having on its top surface upstanding transverse guiding ribs or lugs integral therewith and co-acting with said flanges permitting vertical movement of the bolster and preventing longitudinal shifting thereof, said lugs or ribs and flanges constituting the sole means for preventing lengthwise movement ofthe bolster, substantially as described.

, 5. A side-frame for a railway car-truck having an inwardly-projecting wall integral with said frame and at one vertical edge of its spring pocket, and an inwardly-project ing shelf near the top of the side-frame supported by a bracket beneath it both integral with said frame, legs of an angle bar transom being adapted to lie against and be fastened to said wall and shelf, substantially as described.
